Description

Technical Field

[0001] The present invention relates to the technical field of motors, and particularly to a drive motor for an energy-saving chef machine. Background Art

[0002] As a multi-functional kitchen appliance, a chef machine realizes various food processing functions such as kneading, stirring, and whipping cream through replaceable accessories such as a stirring head and a dough hook. Its core power source is an internally installed drive motor, which usually uses a DC or AC motor. Its working principle is that after the stator winding inside the motor is energized, a rotating magnetic field is generated and interacts with the rotor, driving the output shaft to rotate, and then the power is transmitted to the stirring component through transmission mechanisms such as belts and gears. By adjusting the motor speed and transmission ratio, different food processing requirements can be met.

[0003] A switched reluctance motor for a chef machine disclosed in the existing publication number CN119483103A includes a protective shell, and a control component is arranged on the protective shell. The control component includes a backing plate arranged inside the protective shell, a stator is arranged on the top of the backing plate, the bottom of the stator is rotatably connected with an extension rod, and the extension rod is installed on the backing plate through bolts; a plurality of slide rails are distributed on the outer side of the extension rod, and a contact block is slidably connected to each slide rail. One end of each of the plurality of contact blocks is embedded with a reinforced magnetizing sheet body. A connecting plate is arranged on the top of the stator, a dislocation groove is opened on the outer side of the connecting plate, and a plurality of induction magnets are distributed on the top and bottom inner walls of the dislocation groove, and each induction magnet is respectively located on the top and bottom of the reinforced magnetizing sheet body; although the above technical solution can adjust the internal magnetic field distribution of the motor in real time by changing the waveform, peak value, and effective value of the stator current, and drive the reinforced rotor rod and the connecting shaft to continuously move to the position with the maximum magnetic field strength, so as to realize the influence on the output torque.

[0004] However, in the prior art, when the drive motor operates under high load, such as in working conditions of kneading high-gluten dough for a long time or whipping cream at high speed, a large amount of heat is generated due to the copper loss and iron loss of the stator winding and the rotor, resulting in rapid accumulation of heat inside the motor. If the heat dissipation is not timely, the continuous increase in the motor temperature is likely to cause a decrease in the motor efficiency, an increase in noise, and even shutdown protection. The traditional heat dissipation scheme generally adopts the heat conduction diffusion of the metal casing and the convective heat transfer of the fixed linear air-cooling channel. Some models are supplemented with an axial flow fan for forced air cooling. Although part of the heat can be taken away through air convection, there is still a situation where the heat dissipation path efficiency is insufficient. In the compact space of the cylindrical casing, the fixed linear air-cooling channel can only utilize the axial length of the motor casing. During heat dissipation, the air flow path is short and in a laminar state, and the contact time between the air and the core components is limited, making it difficult to fully take away the heat, resulting in low heat exchange efficiency. Summary of the Invention

[0005] The object of the present invention is to provide a drive motor for an energy-saving chef machine, so as to solve the problem that the drive motor for the energy-saving chef machine has insufficient heat dissipation due to the low heat dissipation efficiency of the fixed linear air-cooling channel and the insufficient air flow turbulence effect in the background art.

[0006] A drive motor for an energy-saving chef machine provided by the present invention adopts the following technical solutions: A drive motor for an energy-saving chef machine is applied to an energy-saving chef machine and includes a motor main body. The motor main body includes a housing arranged in the energy-saving chef machine and a core component arranged in the housing; It further includes multiple groups of heat dissipation units. The multiple groups of heat dissipation units are evenly distributed at equal intervals along the circumferential direction of the inner wall of the housing. Each group of the heat dissipation units includes a flexible plate slidably attached to the inner wall of the housing, elastic connectors fixedly connected to both ends of the flexible plate, a clamping member fixedly connected to the other ends of the elastic connectors, and a fixed seat fixedly installed on the inner wall of the housing. The clamping member is rotatably connected to the fixed seat through a rotating shaft. A positioning wheel is abutted against the middle of one side of the flexible plate, and the positioning wheel is fixedly connected to the inner wall of the housing. Driving wheels are symmetrically abutted against the upper and lower sides of the other side of the flexible plate. A sliding column is fixedly connected to the driving wheel and slides along the inner wall of the housing. Tracks corresponding to the sliding columns one by one are provided on the inner wall of the housing; The sliding column is slidably connected in the corresponding track and extends to the outside of the housing. A sealing ring fixedly connected to the sliding column is rotatably sleeved outside the housing.

[0007] Furthermore, a temperature sensing unit is arranged on the inner wall of the housing. The temperature sensing unit includes a heat conduction cavity hinged to the inner wall of the housing, a piston plate slidably connected in the heat conduction cavity, and a transmission rod fixedly connected to the piston plate. A connecting rod is hinged between the other end of the transmission rod and the corresponding driving wheel. An expansion unit is arranged in the heat conduction cavity; In the initial state, a linear air-cooling channel is formed between adjacent flexible plates. After the expansion unit is heated and expands, it pushes the piston plate to move, so that the driving wheel abuts against the flexible plate to deform into an S shape, and an S-shaped air-cooling channel is formed between adjacent flexible plates.

[0008] Furthermore, a spring is arranged on the transmission rod, and both ends of the spring respectively abut against the inner wall of the heat conduction cavity and the piston plate.

[0009] Furthermore, the expansion unit is an airbag arranged in the heat conduction cavity, and the airbag is filled with a thermally expandable gas.

[0010] Furthermore, multiple groups of air inlets are provided in the circumferential direction of the bottom edge of the housing. An adjusting unit is arranged in the air inlets. The adjusting unit includes a baffle rotatably connected in the air inlets through a shaft rod, and multiple groups of ventilation holes are provided on the baffle.

[0011] Furthermore, one end of the shaft extends outside the casing and is fixedly connected to a connecting arm, a sliding groove is provided on the connecting arm, a sliding rod is slidably connected in the sliding groove, a ring is rotatably sleeved outside the casing, and the sliding rod is fixedly connected to the ring.

[0012] Furthermore, the collar is fixedly connected to one group of adjacent sealing rings, and the collar is driven to rotate synchronously through the rotation of the sealing ring.

[0013] Furthermore, a limiting support plate is fixedly connected inside the air inlet, and when the baffle is completely closed, one side of its bottom is in contact with the limiting support plate.

[0014] Furthermore, the plurality of groups of air inlets are respectively located between adjacent flexible plates, and an air outlet channel is also provided on the housing.

[0015] Furthermore, torsion springs are provided at both ends of the rotating shaft, and both ends of the torsion springs are respectively fixed on the clamping member and the fixing seat.

[0016] Beneficial effects of the present invention: By providing a heat dissipation unit and a temperature sensing unit, dynamic adjustment of the air cooling channel is achieved. The temperature sensing unit drives the flexible plate in the heat dissipation unit to switch between a straight shape and an S shape according to the temperature changes of the movement components. When the load is low, the straight air cooling channel is maintained to meet the basic heat dissipation requirements and avoid excessive heat dissipation. When the load is high, the thermal expansion gas controls the deployment of the airbag, pushing the flexible plate to form an S-shaped air cooling channel. The S-shaped air cooling channel significantly prolongs the residence time of the airflow in the heat dissipation area through the curved and folded path, so that the air is in contact with the movement components for a longer time and can take away the heat more fully. At the same time, the bends of the S-shaped air cooling channel force the airflow to generate turbulence to break the boundary layer, avoid local heat accumulation, and improve the heat dissipation efficiency.

[0017] By setting up an adjustment unit, adaptive control of the ventilation volume of the air inlet is achieved. When the load is low, the outside air enters the casing through the ventilation holes, limiting the air intake to avoid excessive heat dissipation and playing a dust-proof role. When the load is high, the baffles are opened, and multiple groups of baffles are distributed in a spiral shape along the circumference of the bottom of the casing, so that the outside air can enter the casing quickly and in large quantities along the spirally distributed baffles, forming high-speed turbulence in the S-shaped air cooling channel, thereby enhancing the heat dissipation effect.

Detailed implementation manners

[0020] To make the above objects, features and advantages of the present invention more obvious and understandable, the following will describe the detailed implementation manners of the present invention in conjunction with the drawings of the specification.

[0021] Refer to Figures 1 - 3, the present invention provides a drive motor for an energy-saving chef machine, which is applied to an energy-saving chef machine 100 and includes a motor main body 200. The motor main body 200 includes a housing 201 disposed within the energy-saving chef machine 100 and a core component 202 disposed within the housing 201. The core component 202 includes a stator winding and a rotor component.

[0022] Refer to Figures 3 - 7 , it further includes multiple groups of heat dissipation units 300. The multiple groups of heat dissipation units 300 are evenly distributed at equal intervals along the circumferential direction of the inner wall of the housing 201. Each group of heat dissipation units 300 includes a flexible plate 301 that slidably fits against the inner wall of the housing 201, elastic connectors 302 fixedly connected to both ends of the flexible plate 301, a clamping member 303 fixedly connected to the other ends of the elastic connectors 302, and a fixed seat 304 fixedly installed on the inner wall of the housing 201. The clamping member 303 is rotatably connected to the fixed seat 304 through a rotating shaft 305. Both ends of the rotating shaft 305 are provided with torsion springs 3051, and both ends of the torsion springs 3051 are respectively fixed to the clamping member 303 and the fixed seat 304. The middle part of one side of the flexible plate 301 abuts against a positioning wheel 306, and the positioning wheel 306 is fixedly connected to the inner wall of the housing 201. The upper and lower sides of the other side of the flexible plate 301 symmetrically abut against a driving wheel 307. A sliding column 308 that slides along the inner wall of the housing 201 is fixedly connected to the driving wheel 307. The inner wall of the housing 201 is provided with tracks 309 corresponding to the sliding columns 308 one by one. The sliding columns 308 are slidably connected within the corresponding tracks 309 and extend outside the housing 201. A sealing ring 310 rotatably sleeved outside the housing 201 and fixedly connected to the sliding columns 308 is provided. When the sliding columns 308 are driven by a driving force to slide along the tracks 309, the driving wheels 307 squeeze the flexible plate 301 accordingly. At this time, with the positioning wheel 306 as a fulcrum, the flexible plate 301 is forced to bend, and the elastic connectors 302 are stretched through the articulated swing of the clamping member 303, finally making the flexible plate 301 in an S shape. Synchronously, the sealing ring 310 is driven to rotate around the outer wall of the housing 201 through the displacement of the sliding columns 308.

[0023] Refer to Figures 4 - 5 and Figures 8 - 9, a temperature sensing unit 400 is provided on the inner wall of the casing 201. Specifically, two sets of temperature sensing units 400 are provided, and the two sets of temperature sensing units 400 are symmetrically arranged at the upper and lower positions on one side of the inner wall of the casing 201. The temperature sensing unit 400 includes a heat conduction cavity 401 hinged to the inner wall of the casing 201, a piston plate 402 slidably connected in the heat conduction cavity 401, and a transmission rod 403 fixedly connected to the piston plate 402. A connecting rod 404 is hinged between the other end of the transmission rod 403 and the corresponding driving wheel 307. An expansion unit 405 is provided in the heat conduction cavity 401. Specifically, the expansion unit 405 is an airbag provided in the heat conduction cavity 401. One end of the airbag is fixed to the inner wall of the heat conduction cavity 401, and the other end of the airbag contacts the piston plate 402. The airbag is filled with a thermally expandable gas, and the thermally expandable gas can be ammonia, nitrogen or air.

[0024] In the initial state, the flexible plate 301 maintains a straight shape under the tension of the elastic connecting member 302 and the restraint of the positioning wheel 306. A linear air cooling channel is formed between adjacent flexible plates 301 to meet the basic heat dissipation requirements under low load and avoid excessive heat dissipation. When the motor load increases and the temperature inside the movement assembly 202 rises, the heat is transferred to the thermally expandable gas in the airbag through the heat conduction cavity 401. The thermally expandable gas expands when heated, causing the airbag to unfold and push the piston plate 402 to slide axially along the heat conduction cavity 401. The driving wheel 307 is abutted through the transmission rod 403 and the connecting rod 404 to slide along the direction of the track 309. The sliding of the driving wheel 307 causes symmetric thrusts on both sides of the flexible plate 301. Due to the limiting effect of the middle positioning wheel 306, the flexible plate 301 undergoes a bending deformation, changing from the initial straight state to an S shape. The S-shaped air cooling channel formed by adjacent two sets of flexible plates 301 changes the air flow path from axial linear flow to spiral flow, thereby further prolonging the residence time of the air flow in the heat dissipation area and improving the heat dissipation effect.

[0025] Refer to Figure 8 , a spring 406 is provided on the transmission rod 403. The two ends of the spring 406 respectively abut against the inner wall of the heat conduction cavity 401 and the piston plate 402. When the motor load decreases and the temperature drops, the thermally expandable gas in the airbag contracts, and the piston plate 402 returns to the initial position under the pulling force of the spring 406.

[0026] Refer to Figures 10 - 14 , a plurality of groups of air inlets 203 are opened in the circumferential direction of the bottom edge of the casing 201. An adjusting unit 500 is provided in the air inlets 203. The adjusting unit 500 includes a baffle 501 rotatably connected in the air inlets 203 through a shaft rod 502. A plurality of groups of ventilation holes are opened on the baffle 501. The plurality of groups of air inlets 203 are respectively located between adjacent flexible plates 301. Refer to Figure 3 , an air outlet channel 204 is also opened on the casing 201.

[0027] One end of the shaft rod 502 extends outside the casing 201 and is fixedly connected with an adapter arm 503. A chute 504 is formed in the adapter arm 503, and a sliding rod 505 is slidably connected in the chute 504. A collar 506 is rotatably sleeved outside the casing 201. The sliding rod 505 is fixedly connected to the collar 506. The collar 506 is fixedly connected with one group of adjacent sealing rings 310. The rotation of the sealing ring 310 drives the collar 506 to rotate synchronously.

[0028] When the motor is running at low load, outside air enters the interior of the casing 201 through the ventilation holes, flows through the linear air-cooling channel at a lower flow rate, and takes away a small amount of heat generated by the motor running at low load. When the motor switches to the high-load running state, the core component 202 generates a large amount of heat. The expansion unit 405 expands due to heat, pushing the piston plate 402 to move. While the sliding column 308 slides, the sealing ring 310 fixedly connected thereto rotates synchronously. Since the collar 506 is fixedly connected with the sealing ring 310, the collar 506 rotates accordingly, causing the sliding rod 505 to slide in the chute 504, driving the adapter arm 503 and the shaft rod 502 to rotate, so that the baffle 501 rotates to the open state. At this time, multiple baffles 501 are spirally distributed along the circumferential direction of the bottom of the casing 201. Outside air can enter the casing 201 quickly in large quantities along the spirally distributed baffles 501, forming a high-speed turbulent flow in the S-shaped air-cooling channel, enhancing the heat dissipation effect.

[0029] A limit support plate 507 is fixedly connected in the air inlet 203. When the baffle 501 is completely closed, one side of its bottom fits with the limit support plate 507. The limit support plate 507 fitting with the bottom side edge of the baffle 501 serves to support and limit the baffle 501 in the closed state.

[0030] The present invention provides an operating principle of a drive motor for an energy-saving cooking machine: When the motor operates at a low load, the initial pre-tightening force of the torsion spring 3051 causes the flexible plate 301 to maintain a straight shape under the tension of the elastic connecting member 302 and the restraint of the positioning wheel 306. A straight air-cooling channel is formed between adjacent flexible plates 301. At this time, external air enters through the ventilation holes at a relatively low flow rate, taking away a small amount of heat generated by the motor. When the motor switches to a high load, the temperature of the movement assembly 202 rises, and the heat is transferred to the airbag of the expansion unit 405 through the heat-conducting cavity 401. The thermally expanded gas expands due to heat, and the airbag unfolds to push the piston plate 402 to slide axially. The transmission rod 403 and the connecting rod 404 drive the driving wheel 307 to drive the sliding column 308 to slide along the track 309. The positioning wheel 306 acts as a fulcrum to make the flexible plate 301 bend into an S shape, and an S-shaped air-cooling channel is formed between adjacent flexible plates 301. At the same time, the displacement of the sliding column 308 drives the sealing ring 310 to rotate. Through the cooperation of the collar 506, the sliding rod 505 and the connecting arm 503, the baffle 501 rotates to the open state, and multiple groups of baffles 501 are spirally distributed along the circumferential direction of the bottom of the housing 201. At this time, a large amount of external air enters quickly, forming a high-speed turbulent flow in the S-shaped air-cooling channel, greatly enhancing the heat dissipation effect.

[0031] When the motor switches from a high load to a low load, although the heat generation rate of the movement assembly 202 drops suddenly, the thermally expanded gas in the airbag cannot shrink instantaneously and remains in an expanded state for a short period of time. During this period, the piston plate 402 continues to be pushed by the gas, maintaining the S-shaped deformation of the flexible plate 301 through the transmission rod 403 and the connecting rod 404, and at the same time keeping the baffle 501 at the open angle, so as to quickly take away the residual heat of the motor until the thermally expanded gas shrinks after dissipating heat through the heat-conducting cavity 401. The piston plate 402 begins to retract under the tension of the spring 406, triggering the reset of the flexible plate 301 and the closing of the baffle 501.

[0032] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
